TOKYO (Reuters) -Bank of Japan (BOJ) Deputy Governor Shinichi Uchida said the central bank will maintain its yield curve control policy from the perspective of sustaining ultra-loose monetary conditions, the Nikkei newspaper reported on Friday. "We want to make the decision from the perspective of how to sustain easy monetary conditions, while taking into account (the policy's) impact on financial intermediation and market function," Uchida was quoted as saying by Nikkei, when asked about the chance of modifying a cap the BOJ sets on long-term interest rates.
